DISCUSSION
 
 
MOISTURE COMING ALONG WITH WEATHER DISTURBANCES CONTINUES TO  
STREAM INTO THE REGION FOR VARIABLE CLOUD COVER AND HIGHER DAYTIME  
RELATIVE HUMIDITY OVERALL. THE AIR WILL REMAIN GENERALLY ON THE STABLE  
TODAY WITH LOW MIXING HEIGHT POTENTIAL NORTHERN DISTRICTS BUT  
TEMPERATURES WILL BE WARMER BY LATE AFTERNOON. MOUNTAIN REGIONS  
HAVE THE BEST CHANCE OF LIGHT PRECIPTATION MAINLY THE CASCADE  
CREST TOWARD THE NORTHERN MOUNTAINS OF WASHINGTON AND IDAHO TOWARD  
THE CANADIAN BORDER. WINDS OVERALL WILL BE LIGHT AT 10 MPH OR  
LESS. THE NEXT WEATHER SYSTEM LOOKS TO BRING RAIN TO THE CASCADES  
AROUND SUNDAY WITH SOME CASCADE GAP WINDS RETURNING MONDAY BUT  
OVERALL IT DOES NOT LOOK LIKE A SIGNIFICANT STORM.
